Mastering Defense and Utility in Diablo 4

Overpower is a new effect in Diablo 4 that works like a critical hit, but scales off health and Fortify. It has a 3% chance of happening on each skill cast and starts at +50% bonus damage. However, it is currently under-tuned and not useful in many endgame builds, except for the Druid's Werebear Pulverize build. Fortify is a stronger effect, and if Blizzard adjusts how Overpower scales with it, it could become more useful.
